摘要：
Rhodium(III)-catalyzed N-directed ortho C-H activation reactions have been developed for the synthesis of unique heterocyclic benzoisothiazoles. Herein, this novel tandem annulation approach can efficiently construct benzoisothiazole compounds from free NH-sulfoximines and alkenes via C-H activation, olefination and subsequent intramolecular aza-Michael cyclization.
